CHAIR ADJUSTMENT INSTRUCTIONS
To maximize the ergonomic benefits of this chair, it is essential to understand how the controls function and how they affect your posture.
ADJUST THE
HEIGHT RANGE:
The lever under the seat on the right side pneumatically adjusts
the height of the seat over a range of about 8". The proper height
should be determined by a combination of variables: the height
of the work surface, the task to be performed and your body size.
Typically, the chair should be high enough so your arms form a
90
o
angle at the elbow or slightly greater. This allows for better
circulation in the shoulders and neck area and also reduces the
amount of fatigue in the forearms and hands. The feet should lie
flat on the ground or footring. To help insure good posture,
maintain a 90
o
angle at the bend of the knees.
ADJUST THE BACK
HEIGHT AND DEPTH:
Loosen the backrest height adjustment knob behind the seat.
Slide the backrest assembly up or down and adjust the height
of the back, which has a lumbar support curve to it. The knob
under the seat allows you to adjust the backrest forward and
back. Sit centered on the seat. The curve in the backrest should
fit into the small of your back. This will reduce the pressure on
the spinal discs, especially in the lumbar area.
MAINTENANCE
The pneumatic lift in the Cylinder is permanently
lubricated at the factory and needs no further
lubrication.
NEVER LUBRICATE THE
PNEUMATIC LIFT
. Do not remove clip from
